The straight lines y = m1 x + c1 and y = m2x + c2 will meet the co-ordinate axis in concyclic points if –

A

m1 m2 = 2

B

c1 c2 = 2

C

m1 m2 = 1

D

c1 c2 = 1

Answer

m1 m2 = 1

Explanation

Solution

y = m1x + c1 & y = m2 x + c2

Equation of conic section

(m1 x – y +c1) (m2 x – y + c2) + l xy = 0

Represents circle coffe. of x2 = coffe. of y2

m1m2 = 1
